Holy cow, Great Lakes Orchids sells their Bletilla for $18.95! And that's for plants in 3"x3" pots. But they don't even have any available. This company appears to deal mostly with orchids that are practically impossible to grow in the south, at least outdoors.
Spangle Creek Labs is the same, growing seedlings that are best grown I the northern tier of states. At least they do warn us Southerners that their orchids are not well suited (or even impossible) to grow down here.
